This conference gets a bit bigger each year, but the organizers make a great effort to keep the small conference feel. It also has many level-100 tutorials, and is both socially and technically welcoming for py-newbies.

Open space sessions (everything from software development to Settlers) and poster sessions happen every night, tutorials run two days prior, and code sprints run for a few days after the conference. It promises to be a great learning and social experience you should not miss.
